II. PROJECT PURPOSE AND NEED
A. Legislation
This project was approved by the General Funding Phase Year Amount
Assembly as part of the Bridge Replacement BRO D 2014 $200,000
Program in the 2012 Biennal Highway Plan. BRO R 2015 $100,000
BRO U 2015 $50,000
BRO C 2016 $600,000
B. Project Status
Design Funds have been requested but not authorized at this time. There are no other projects in this area at this
time.
C. System Linkage
KY 2021 is a local road that serves residents of theBig Willard community as well as the primary access to the Little
Beech Historic Site. This route connects to KY 451 and then to the Hal Rogers Parkway and KY 80 corridors.
D. Modal Interrelationships
There are currently no Modal connections in this area.
E. Social Demands & Economic Development
There are currently no new plans for further commercial or industrial type development in this area. It is anticipated
that this route will continue to function as a local residential route.
F. Transportation Demand
The usage demand for this road is expected to stay the same for the foreseeable future.

II. PROJECT PURPOSE AND NEED (cont.)
G. Capacity
There are no known capacity issues at this time nor are any expected in the near future.
H. Safety
A review of the Kentucky State Police Collision Database shows no collisions along the project section.
I. Roadway Deficiencies
KY 2021 is a narrow two lane roadway with little to no shoulders. It has numerous substandard horizontal and
vertical curves. The bridge is considered both structurally deficient and functionally obsolete.
Purpose and Need Statement:
Need: This project will replace a structurally deficient (SR 46.8) bridge along KY 2021. This replacement is needed to
ensure a continued linkage for residents of this community to the rest of the highway system.
Purpose: The purpose of this project is to replace a Structurally deficient, functionally obsolete bridge in order to
allow continued usage of the roadway for residents of the Big Willard area.

IV. POSSIBLE ALTERNATIVES
A. Alternative 1: No Build
This alternate will not address the identified purpose and need.
B. Alternative 2
This alternate proposes to reconstruct the new bridge in the same location as the existing using part width
construction methods. This alternate appears to have the least impact on both RW and Utilities but would take longer
to complete.
Planning Level Cost Estimate: Phase Estimate
Design $200,000
R/W $25,000
Utilities $50,000
Const $550,000
Total $825,000

IV. POSSIBLE ALTERNATIVES (cont.)
B. Alternative #3
This alternate proposes to construct the new bridge in the same place as the existing only this alternate would utilize
a temporary diversion for Maintenance of Traffic. The diversion is proposed on the north side due to lower potential
cost associated with RW.
Planning Level Cost Estimate: Phase Estimate
Design $200,000
R/W $75,000
Utilities $50,000
Const $600,000
Total $925,000
V. Summary
